Abstract

We present experimental evidence to demonstrate the feasibility of a promising new quasi-phase-matching technique in AlGaAs multiple-quantum-well waveguides. Non-phase-matched second-harmonic-generation measurements indicate that, for sub-half-bandgap excitation near 1.5  µm, quantum-well intermixing by impurity-free vacancy disordering results in a reduction of the nonlinear susceptibility.
